"I was referred to Roney at Babylon Builders by my realtor in the Bay Area. I am seeking some insight and advice on a property pending purchase. Roney was prompt in response and truly went above and beyond in answering my questions and explaining my various options. Thank you, Ron! I look forward to meeting with you and your team in the very near future."

"I had an aluminum door canopy that pulled completely away from the house due to the weight of excessive snow. Might Be Helpful explained how the canopy could be re-installed and made stronger, even showing me the hardware to be used. I am a rather exacting customer but Might Be Helpful got the canopy up and it looks great--just like I wanted. A bit of re-painting was done; the job site was left neat and clean; and a dried-up can of paint was disposed of for me which I quite appreciated."

Barndominium Builders FAQs, answered by experts

The foundation for a pole barn should be at least 36 inches thick to ensure that the piers won’t shift from frost heave.

Your foundation contractor will first need to remove the topsoil and any vegetation within 4 feet of the area around the barn. They’ll need to ensure they have clear access to the site to begin excavation, after which they can begin construction.

The best lumber for building will be the strongest and most eco-friendly wood your budget allows. That being said, Douglas fir, pine, oak, and maple are all common building materials. Contractors will use a strong, inexpensive wood to frame a house or other structure and finer woods like mahogany for detail work. 

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

The lifespan of a barn is typically 40 to 60 years, but with skillful construction and proper maintenance, it can last up to 100 years. The actual lifespan depends on several factors, including the barn type, materials, usage, and climate. For example, the posts of a pole barn should last 50 years or longer, but if the structure is used for livestock in a rainy climate, it may rot within the first decade. Custom designs with high-end materials tend to last the longest. To get the best estimate for your barn's lifespan, you should consider its material type and intended use.
